will be using small items‚ such as candies‚ to represent chemical compounds undergoing a reaction. Draw a line down the middle of a sheet of paper and label the left side of the paper “R” for reactants and the right side “P” for products. R P To represent molecules that are reactants‚ you will place candies on the reactant side of the paper; products will be candies on the product side of the paper. Reactions will be represented by moving a candy from one side of the paper to the other. Part I

Copper Reactions Rodney Jay C. Ridao Florencio Louis Pascual Relao De La Salle University- Dasmariñas Dasmariñas Cavite Philippines ABSTRACT The Copper Reactions experiment was demonstrate by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagent were being added. It was also demonstrated to practice the common laboratory

Objectives 1. To separate a mixture of an acid and a neutral compound into its component by extraction. 2. To determine the melting point and the yield of the benzoic acid and the unknown sample. 3. To determine the unknown sample whether is is Trimethylmethanol or 1‚2‚4‚5-Tetrachlorobenzene. Introduction Extraction is a process of transferring a solute from one solvent to another. It is usually used to separate one or more components from a mixture. Diethyl ether‚ dichloromethane

nucleophile for attack towards the phosphorus atom of the phosphate group bonded to the 3’-C end of the same ribonuclease sugar. During this process‚ it causes His12 to become protonated‚ thus causing it to become acidic. 21-22 Conversely‚ His119 acts as an acid to facilitate the departure of the leaving 3’-monophosphate group. This is achieved when the acidic imidazolium ion of His119 simultaneously protonate the oxygen of the phosphate oxyanion group. 23 This leads to the formation of 2’‚3’-cyclic phosphorane

acetic acid in white vinegar. 2.0 Theory The concentration is a measurement of relative amounts of solute and solvent. There are many diverse ways of expressing concentration but the most accepted and widely used is molar concentration and regularly referred to as molarity which is defined in mole‚ the amount of solute dissolved in one litre of solution. [pic] In this experiment there are solutions used with accurately known concentrations called standard solutions. The reaction of chemicals
